IPC: H02J7/04
Filed: 1994-08-26
Abstract: PURPOSE: To recover a charging properly of a battery in inconstant discharging of the battery and to regain a rechargeable condition so as to prolong a cycle life. CONSTITUTION: In a process in which charging by means of a charging device 1 and inconstant discharging are repeated, internal impedance of a secondary battery 2 is measured by means of an impedance measuring device 3 when charging is repeated ten times or more, and if the secondary battery 2 is sufficiently provided with charging acceptance ability, this process is repeated.
